SPEED-GOVERNOR.

Specification of Letters Patent.

Application filed April 9,1909. Serial No. 488,985.

To all whom it may concern Be it known that I, HENRY O. BARENZ, residingin Jackson, in the county of WVashington and State of Wisconsin, havein-.: vented new and useful Improvements in Speed-Governors, of whichthe following is a description, reference being had to the chines whichare adapted to drive at predetermined rates-of speed.

The principal object of to provide a speed governor in which a frictiondrive wheel is adapted to be disconnected from the driven mechanism whenthe speed of said driven mechanism is increased above a predeterminedrate.

A further objectof the invention is "to provide a speed governor inwhich portions thereof are capable of adjustment to vary thepredetermined rate of speed desired.

A further object of the invention is to provide a speed governor whichis simple in construction and inexpensive to manufacture and maintain.

With the above, and other objects in view,

the invention consists of the governor and its parts and combinations,and all equivalents thereof.

- In the accompanying drawing, in which the same reference charactersindicate the same parts in all of the views; Figure 1 is a front sideview of the governor shown in connection with the spindle of a creamseparator and a fragment of the frame, parts of the frame and a part ofthe governor being in section; Fig. 2 is a rear side view of thegovernor; and, Fig. 3 is a vertical sectional view thereof taken on line38 of Fig. 2.

Referring to the drawing the numeral 5 indicates a fragment of a creamseparator frame and 6 the spindle thereof having a worm thread providedon its lower end. This spindle is supported in a suitable bearing 7provided in the frame and is adapted to be rotated at a high rate ofspeed by means of a worm wheel 8 in mesh with the worm thread. The wormwheel is loosely mounted on a shaft 9 between a friction wheel 10 and acollar 11 both of which are rigidly connected to the shaft.

the invention is Patented Feb. 13,1912.

Friction bands 12 pivoted to the worm :1

wheel by pivot screws 13 and provided with friction shoes 14 are adaptedto bear against the periphery of the friction wheel 10 and are the meansfor transmitting motion from said wheel to the worm or loose wheel 8.Screw bolts 15 provided with eccentric heads 16 are threaded in andextend through the worm wheel and into lever weights 17 on the oppositeside of the worm wheel and are rigidly connected to-said weights bymeans of jam nuts 18 which look the parts together. The ends of thefriction bands opposite to their pivotal connection with the worm wheelare connected to the eccentric heads of the screw bolts 15 by means ofscrews 19 threaded therein. The free ends of the lever weights areprovided with eyes 20 to which are connected tension springs 21 and theopposite ends of these springs are fastened to nuts 22 threaded onadjusting screws 23. The screws 23 pass loosely through openings 24provided in the lever weights and the heads of the screws are adapted tobear against the shoulders formed by the openings on the opposite sidesof the lever weights.

The operation of the governor is as follows-assuming that the tension ofthe spring has been adjusted to prevent the rotation of the spindle fromrising above a predetermined rate, the rotation of the shaft andfriction wheel will transmit motion to the worm wheel and the spindle bymeans of the engagement of the friction shoes with the friction wheeland this transmission of motion will continue as long as the speed ofrotation does not go above the limit set by the adjusting screws. Ifhowever the speed rises above this limit, the lever weights will beswung outwardly by centrifugal force and overcoming the tension of thesprings will cause the eccentric headed screw bolts to turn and theeccentric portion of each head to swing toward the friction shoe towhich it is connected and move the shoes out of engagement with thefriction wheel and stop the transmission of motion and as soon as therotation of the worm wheel slows down to the desired speed the springswill draw the lever weights inwardly and the friction shoes will againengage the friction wheel as before.

The tension of the springs may be adjusted as desired by turning theadjusting screws with a screw driver without discon necti ng any of theparts. I The threaded connection of the eccentric headed screwbolts'Wlth the Worm Wheel permits the free turnseen that a very simple formof governor is provided which is Well adapted to accomplish the desiredresults.

What I claim as my invention is:

A speed governor, comprising a driven If shaft having a Wheel fastthereon, a Wheel loosely mounted on said shaft, friction bands pivotallyconnected to said loose Wheel and provided With friction shoespositioned v to engage the fast Wheel, bolts extending through the looseWheel and provided With eccentric heads to the peripheries of Which .thefriction bands are connected, lever Weights rigidly connected to thebolts for Copies of this patent may be obtained for turning said boltsto release the friction shoes from engagement With the fast Wheel Whenthe speed of rotation of the loose Wheel increases above a predeterminedrate,

coiled springs connected to the free ends of saidlever Weights, nutsconnected to the opposite ends of said springs, bolts extending throughopenings provided in said lever Weights adjacent to the eccentric headedbolts and threaded to the nuts connected to the springs to adjust thetension of said springs, said springs being connected to both leverWeights to provide for equal tension of both lever Weights underdifferent adjustments of the springs.

In testimony whereof, I afiiX my signature, in presence of tWoWitnesses.
